Background: Garnacha is the world’s most widely planted grape variety although most of it is in Spain. It produces a high alcohol, fruity wine often used for blending. Because it is low in acid, it is susceptible to oxidation. When used in France’s southern Rhone region of Châteauneuf-du-Pape, it takes on heady aromas and spicy, red berry fruit flavors. It is also used extensively in Southern Rhône Rosé and Provence wines because of its acidity. Old vine (more than 50 years old) Garnacha has moderate procution levels in Spain and produces a much fuller-bodied concentrated wine.
